Answer:
B. 1
Step-by-step explanation:
they only cross at one point... look below
Answer:

Step-by-step explanation:
The distance d between a point (m , n ) and a line in the form
Ax + By + C = 0 , is calculated as
d = 
Here (m, n ) = (6, 2 ) and
6x - y = - 3 ( add 3 to both sides )
6x - y + 3 = 0 → A = 6, B = - 1, C = 3
d = 
= 
= 
=
× 
=
← cancel 37 on numerator/ denominator
= 
B is your answer.
Because 7 times 8 is 56 and 7 times 3 is 21.
For this case we have that the area of a circle is given by:

Where:
r: It is the radius of the circle
By clearing the radio we have:

We take the positive value:

The diameter is twice the radius:
